Honestly I think every format needs a community panel separate from Wizards to decide the BnR. I think people forget a lot of the time because Wizards usually does a good enough job most of the time, but when bans run against the bottom line (Oko, Hogaak, etc...) they always seem to come down on the wrong side.
The issue of course is A. Getting Wizards to do it and B. Getting the right people on it. Commander has a community-run panel but it feels like they're far too lax and out-of-touch sometimes.
